HENRICH HBSGEER, OF NEW YURK, N. Y., ASSIGNOR 0F ONE-HALF TO E. C. NEELSEN, 0F

. NEW YORK, N. Y.

To all `whom it may concern:

Be it known that l, HEINRICH Hnsor-nrn, a subject of the Emperor ofGermany, and resident of New York, in the county of New York and Stateof New York, have invented certain new and useful PhotographicApparatus, of which the following is a specification.

The object of my invention is to provide a portable camera attachment ofvery small size which can be conveniently carried about and attached toany ordinary camera, and set and timed to operate automatically inconnection with an adjustable time-exposure mechanism, whereby thephotograp may take either an instantaneous or timeex osure picture ofhimself or other objects.

l, ith these ends in view my invention consists in the peculiar featuresand combinations of ,parts more fully described Ahereinafter and pointedout in the claims.

In the accompanying drawings, Figure 1 is a general view of my inventionas a lied to the shutter of an ordinary camera; ig. 2, a front view ofmy complete device ready for action; Fig. 3, a side elevation of theplate carrying the alarm and time-exposure mechanisms; Fig. 4 is a frontelevation of In complete invention with lthe `face remove the mechanismbeing set for taking a picture; Fig. 5 is the face on which are locatedthe winders, dials and pointers. Fig. 6 is a front elevation, with theface removed, showing the power mechanism sprung and in action and theposition of the parts resulting therefrom. Dotted lines show the closinmechanism released to cl se the shutter; ig. 7, a view showing the poitions of the winders and dials in relat1on to the adjustments shown inthe receding view; Fig. `8, a side elevation, partliy insection,.showing most of the parts on the left-hand side of my device;Fig. 9, a detail vie'w of the clutch mechanism yfor throwing the shutterclosing mechanism, and Fig. 10, a side elevation, partly in section,showing most ofthe parts on the right-hand side of my device.

This apparatus comprehends three princial organismswhich co crate forperforming the three o erations 1n the following order: rst, thetune-mechanism adapted to be set to work for any number of minutes, from1 to 4, in order to allow am le time forthe photographer to leave theinstrument and pose; second, the alarm mechanism which sounds a warningjust. before the shutter Speoication of Letters Patent.

o ens and continues during the exposure; t ird, the shutter closingmechanismwinch closes the shutter and stops the alarm.

The clock-work mechanism of my device is mounted on two circular platesla and 1b inclosed within a circular case 1 like that of an ordinaryalarm clock. To condense the several mechanisms above described withinthe space of a small alarm-clock having the form of a short cylinderclosed at the ends, is regarded as a ver important feature of myinvention,vfor witii device would be too cumbersome and unwieldy for thework of amateurs and others in practicing outdoor or indoor photography.On one side is a face which is provided with the winding handles, dialsand pointers.

40 and 41 indicate the handles, and 42 and 43, the dials.

The alarm mechanism, as seen in Fig. 3, consists of a spring actuatedgear 2 carryin a pawl and ratchet 2a on a shaft'2b revolve by a coiledfiat spring 2C meshing with pinion 3 iixed to gear 4 which in turnmehses with a pinion 5 on a tripping wheel 6, the radiating arms ofwhich trip the projections 7 and 8 on a hammer 9 which plays upon alarge sounder 10. The means for releasing the alarm just before theshutter opens, Figs. 4 and 5,con-

of which have inwardly projecting points 17 .a

and 17 bearing on the cam wheel, the lever 14 serves to release or stopthe alarm hammer 9. The trigger 18 releases a compressing arm 22 forcompressing a bulb, and transmitting pneumatic power to the shutter of acamera, as shown in Fig. 1. The power transmit-ting mechanism remainsidle momentaril while the cam wheel is advancing until t e projection 17on the tail of the pawl-trigger 18 1s' forced into the cam notch 16 bysprin 19, and releases the pawl 29 of trigger 18 om any one of a seriesof notches 20 on wheel 21 fixed on transverse shaft 21a carrying thecompressing arm 22. This arm 22 projects out of the casing and isimpelled by a s iral spring 23 encircling .the shaft 21a on W 'ch outdoing so the whole i' wound by a handle 41.

the compressing arm is mounted. A. compressing cup 23 is hin ed to theedge of a ollow all-shaped bulb older 24 located outside above the topof the case 1. This compressing cu or thimble rests by gravity upon thefree en of the compressing arm in osition to be pushed into the openside o the bulb holder.

25 is an ordinary rubber bulb, bellows or air holder from which a tube26 leads to the camera shutter in the old-and well known way, as seen inFig. 1. This bulb is held in place by means of an open slot 27 and hook28. When the trigger 18 is tripped by the cam wheel 11, the pawl carriedonL the trigger is pulled back with it by a luv-30 through the force ofspring 19, thereby releasing the compressing arm, forcing the cu 23 intothe bulb and transmitting power to t e shutter.

The time-exposure mechanism is located on the right ofthe alarmmechanism, as seen in Fig. 3, and it consists of a large gear 35carrylng a pawl and ratchet 35a, and connected with a train of gears 36,37, 38, and 39, terminating in a fan-wheel governor 40, andbeingactuated by a main-spring 35? v After the shutter has first been 'openedby the power mechanism, itis allowed to close when the power iswithdrawn from it, in the manner now to be described. The bulb-holder 24is secured to the free end of a rock-arm 50 on a rock-shaft 51 encircledby a coil spring 52, and the arin is rigidly held to the action of thecompress-A ing arm 22 by a ratchet 53 on shaft 51, in con-4 junctionwith a spring-actuated pawl 54 on a pawl-trigger 55, the pawl beingreleased. by a spring 57 and a lug 56 on the short end of the trig er.This spring 57 holds the long arm of t e trigger to the action of atripping cam 58, the latter beingactuated by a main spring 35b and trainof gears 5,9, 60, 61, and

62", (Fig. 4). The cam 58 is fixed to turn hard with its center withinthe gear 61, like the other tripping cam 11 for the pur ose of adjustingit with the ointer 43b of 'al 43, the pointer being fixe to the cam,wqhereby it may be setto operate earlier or later. During the reliminaryrunning of the timing mechanism, that is to say, before the alarm is setoli, and before the compressing arm is tri ped, the shutter-closingmechanism, whic is held out of action'through the medium of an arm 62loosely pinned to the long arm of triI ger 18, has u on its righthandend a wege 63a which- 'es beneath a thin exible clutch-thrower 64, thefree end of which passes astride the hub of trip ing cam 58, and throwsthe clutch teeth 65 ig. 9) on the underside of cam 58 in engagement withsimilar teeth upon the upper part. of gear 61. When the. trigger 18 istripped, the wedge is pushed out from under said clutch-thrower 64. Thismovement locks closes,

through the action of an extension 68 on the tail of the trigger 55which extension lifts one end of a rock-arm 69 causing its opposite endto press down upon a similar extension 70 on the alarm controlling lever14. This lever 14 stops the alarm by moving its upper inturned endinward in the way of teeth 9a on a crown-wheel 9. The inturned end ofthe lever 14 projects through a slot 9b in the plate la, as seen moreclearly in Fig. 8.

The whole machinery is thrown in and out of action by a stop 71 shown inFigs. 6 and 10, vwhich stop is rojected in and out of the 'way of thefan w eel 40 by a hinged arm 72 extending `out of an arc-shaped slot 74.When this arm 72 is swung to the left it presses the stop 71 back out ofthe path of the fan-wheel and allows the machinery to work. A reversemovement will Stop the machinery.

Thus constructed the operation of m device may be brieily summed up asfo ows: The alarm and time exposure mechanisms should iirst be wound bythe handles 40 and 41. The pointer or dial42 should now be moved aroundto any one of the figures from 1 to 5 which indicate the number ofminutes which will ela se before vthe shutter will Work. This give thephoto rapher time to leave the instrument and ta e a picture of himselfin any desired position, such as running, jumping, swimmin etc. If atime exposure 1s desired, it can e had by setting the pointer 43h ofdial 43 at any one of the divislons from 0 to 60, re resenting thenumber of seconds that be allowed. The apparatus may now be laced uponthe ground near the camera, an the compressing arm pulled back byhanduntil the triger holds it. The bulb holder is also brou ht orward byhand into set position. starting and stopping arm 72 should be thrownfrom right to left to start the machinery golng. I t will continue to gountil the alarm releasing lever operates, then the alarm begins to soundand continues while the photograph is being taken. The further revoution of the cam wheel 11 trips the compress' arm and works the shutter..When the bu b holder drops back, the shutter taken.

scares Having thus described my invention, what I claim and desire tosecure by Letters Patent, is:

1. ln a portable camera attachment, an automatic time-mechanism and anautomatic alarm-mechanism, in 'combination with a time-exposuremechanism, means for graduating the time eX osure mechanism, a casingwithin which a of said mechanisms are housed, an exterior bulb-holder,and means for compressing a' bulb within the holder.

2. in a portable cameraY attachment, an automatic tnmng' mechanism, 1ncombination with an alarm mechanism, a power ,mechanisrm and abulb-holder which automatically recedesfrom the power-mechanism,substantially as described.

3. Ina camera attachment, the combination' with an alarm and timinmechanism, of a power-mechanism, a bulb-l older held to the action ofthe power mechanism, and means for retreating the bulb-holder from thepower mechanism, substantially as described.

4. In a camera attachment, a power mechanism, and a bulb-holder, incombination with means for moving the bulb-holder bodily, substantiallyas described.

5. In a camera attachment, a shutterworker havin an automatic closingmechanism,` in com ination with an alarm mechanism thrown out of actionby the closing mechanism.
